Question

A school bus takes 45 minutes to cover a distance of 27 km calculate its speed

Answer 1

Answer:

Speed of the bus is 36 km./hr.

Step-by-step explanation:

Given:

Time taken by bus = 45 min.

1 min. = 1/ 60 hr

45 min. = 45 /60 =3 / 4 hr

Distance covered = 27 km.

Speed of the bus = distance / time

                              = 27 ÷ ( 3/4)

                              = 27 × (4/ 3)

                              = 9 × 4 = 36 km/hr.
